Problemas con fracciones

Suma de fracciones de una misma unidad

Cuando tienes diferentes partes de un mismo grupo total, puedes sumar las fracciones para saber cuánto representan juntas. Solo tienes que asegurarte de que tengan el mismo denominador.

Ejemplo práctico: En tu clase, 1/3 de los estudiantes se apuntan a baloncesto y 1/4 a ballet. Para saber qué fracción total hace actividades extraescolares, sumas: 1/3 + 1/4 = 4/12 + 3/12 = 7/12 de la clase.

¡Recuerda! Siempre busca el denominador común antes de sumar. En este caso, 12 es múltiplo tanto de 3 como de 4.

Fracción de otra fracción

A veces necesitas calcular una fracción de lo que queda después de otra fracción. Esto pasa cuando una parte se toma del resto, no del total original.

Ejemplo: 1/3 de tu clase hace baloncesto, y 1/4 del resto hace ballet. Para calcular la fracción de ballet: primero encuentras el resto (2/3), luego calculas 1/4 de ese resto. La operación es: 2/3 ÷ 4 = 2/3 × 1/4 = 1/6 de la clase hace ballet.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.
